(25) باب الأَمْرِ بِالاِسْتِغْفَارِ فِي الْكُسُوفِ
It was narrated that Abu Musa said:
"There was an eclipse of the sun, and the Messenger of Allah (ﷺ) got up in a rush, fearing that it might be the Hour. He went to the masjid, where he stood and prayed, standing, bowing and prostrating for the longest time that I ever saw him do in prayer. Then he said: 'These signs that Allah (SWT) sends do not occur for the death or birth of anyone, but Allah (SWT) sends them to strike fear into His slaves. If you see any of these things, then hasten to remember Him, call upon Him supplicate and ask for His forgiveness.'"
